ASA Color E6B Flight Computer
Flight planning starts with numbers that have to be right the first time, and the tool in your kneeboard matters. From the metal E6B that’s survived generations of student pilots to digital calculators that handle wind correction in seconds, today’s cockpit options run a wide range. This list breaks down eight flight computers covering manual slide rules, rotating plotters, full kits, and modern digital helpers. You’ll see which tools make sense for ground school, which hold up under cockpit heat, and where premium aluminum beats budget plastic. By the end, the right companion for your training or cross-country work should be obvious.
The classic ASA E6B has anchored flight bags for decades, and for good reason. At six inches in diameter with a solid metal body, it feels substantial in your hand and shrugs off the inevitable drops into a briefcase or seat pocket. The circular design pairs a slide-rule calculator on one side with a wind triangle setup on the other, covering every standard computation a private pilot or instrument student needs.
For student pilots working through FAA written exams or instructors teaching ground school, this is the reference tool most checkrides reference. Unlike digital options we’ll see later, it asks for your attention, which builds real understanding of the math. Most owners find the lettering legible, though aging eyes may need good light in the cockpit.
Useful Touches
- Six-inch diameter gives plenty of scale for accurate wind triangle work without being bulky.
- Solid metal construction handles the daily abuse of a flight bag or briefcase.
- Recognized across flight schools, so instructors rarely object to its use during training.
- Manual operation builds the mental math that makes digital tools easier to verify later.
Things To Consider
- The metal body weighs noticeably more than plastic or digital alternatives.
- Older lettering styles can be hard to read in dim cockpit lighting.
- Takes longer than a digital unit for complex fuel planning sequences.
Key Specs
Who Should Grab It
Student pilots preparing for FAA written exams and instructors building a durable classroom reference.
Reach For A Different Pick When
If speed on multiple fuel and time calcs matters more than tactile learning, the ASA CX-3 Flight Computer gets you answers faster.
The SimCoach plotter was built with summer cockpits in mind, since its plastic body tolerates temperatures up to sixty degrees Celsius without warping. For pilots flying unpressurized Cessnas or Cherokees in desert heat, that spec alone justifies the spot in your chart case. The rotating azimuth dial lets you measure true courses directly off sectional, terminal area, and WAC charts.
The front face reads in nautical miles while the back handles statute miles, so cross-country planners working with mixed references don’t have to swap tools. Compared to the metal E6B above, this is a lighter companion that pairs naturally with any calculator. For most student pilots building out a kneeboard kit, the chart-reading practicality here is the real draw.
Notable Upsides
- Plastic body rated for sixty degree Celsius cabin temps without warping.
- Rotating dial measures courses on sectional, terminal area, and WAC charts.
- Nautical miles on front, statute miles on back, covering both common references.
Honest Caveats
- Plastic construction feels lighter than the ASA E6B Metal Flight Computer and may scratch over time.
- Less durable if it gets jammed into an overstuffed flight bag next to heavy headsets.
Whose Shelf It Belongs On
VFR pilots flying in warm climates who need reliable chart work from sectional to terminal area scales.
A Better Fit Elsewhere
For students who also need the actual calculator side, the SimCoach Aviation Plotter Kit bundles a matching E6B in one package.
Where the rotating model targets flexibility, the fixed SimCoach plotter keeps things simple and affordable. Three scales are printed clearly on each side, covering sectional at 1:500,000, WAC at 1:1,000,000, and terminal area charts at 1:250,000. For ground school students who don’t need a rotating azimuth yet, that’s often plenty.
The resin material is treated to resist fading and melting under typical cabin conditions, so the markings stay legible across a long ownership window. You may find this fixed version easier to align on a folded chart since there’s no dial to spin out of position. Compared to the rotating version reviewed earlier, you trade the moving azimuth for a cleaner, more rigid reference tool.
Well-Handled Touches
- Three common chart scales printed on a double-sided layout for quick access.
- Resin build resists fading and surface wear over extended use.
- Lower price point makes it a reasonable starter plotter for new students.
Points To Keep In Mind
- No rotating dial, so true course measurements take an extra step.
- Resin can still scuff if tossed loosely into a chart case with metal tools.

Swap It Out When
When you start measuring true courses on actual cross-country flights, the SimCoach Rotating Aviation Navigation Plotter is the smarter upgrade.
For VFR pilots who want to consolidate several tools into one, this Destination Departure plotter crams eight measurement scales into a single rotating slide rule. Front side reads nautical miles while the back switches to statute miles, plus scales for sectional, WAC, and terminal area charts cover the standard references. There’s also a magnetic variation scale for converting true to magnetic course without a second tool.
The appeal here is consolidation: one device handles chart measurement and a chunk of the math work that would otherwise need a separate E6B. Most students and VFR pilots appreciate the layout once they’ve internalized which scale lives where. Compared to the fixed SimCoach above, you gain rotation and scale density at the cost of a slightly larger footprint.
The Upside
- Eight scales cover nautical, statute, and magnetic variation work in one tool.
- Rotating slide rule combines plotter and calculator duties for VFR planning.
- Compatible with sectional, WAC, and terminal area charts without swapping tools.
- Reduces kneeboard clutter by merging functions normally split between devices.
Potential Drawbacks
- More scales mean a steeper learning curve for first-time students.
- Larger footprint than a basic fixed plotter.
Best Suited To

Where A Sibling Pick Shines
For dedicated wind correction and fuel math on the calculator side, the ASA CX-3 Flight Computer is the better digital partner.
The CX-3 swaps the tactile slide rule for a digital interface, and it does so without compromising on exam compatibility. The menus are organized to follow the natural order of flight planning, so wind correction, true airspeed, and fuel burn sit in the sequence you’ll actually use them. Both FAA and Canadian pilot, mechanic, and dispatcher knowledge exams accept it.
For students who dread manual interpolation or instructors tired of watching trainees fumble the slide rule, the CX-3 removes that friction. The trade-off is a battery-powered device, so you carry spares. Most professional pilots find it shaves meaningful minutes off complex cross-country calculations compared to metal alternatives like the ASA E6B Metal Flight Computer above.
A Favorable Mix
- Digital calculations eliminate manual slide rule errors during exams.
- Accepted on FAA and Canadian knowledge exams for pilots, mechanics, and dispatchers.
- Menu order mirrors a natural flight planning workflow for easier recall.
- Faster results on multi-step fuel and time problems than manual E6B methods.
Trade Offs
- Requires batteries, so a dead cell mid-flight means no calculations.
- Less helpful for learning the underlying math versus a manual E6B.
Perfect Match For
Busy student pilots, professional crews, and dispatcher candidates who need reliable exam-approved results fast.
Skip It When
Those building foundational math skills may prefer starting with the SimCoach Mechanical E6B Flight Computer for Pilots before going digital.

Consider Something Else When
Pilots wanting a more refined E6B body should look at the ASA Color E6B Flight Computer for tactile premium feel.
The standalone SimCoach E6B strips the experience down to its teaching essentials. One side handles the circular slide rule for time, speed, and distance while the other side focuses on wind correction angle, true heading, and ground speed. The double-sided layout lets students see cause and effect side-by-side as they work through problems.
Most student pilots find this mechanical approach forces engagement with the math, which builds long-term understanding that a digital calculator can hide. There’s no battery to die during a long ground school session or checkride. Compared to the aluminum ASA E6B, you trade premium heft for a lighter, more approachable price point that fits a first-semester budget.
Good Reasons To Consider
- Manual design builds real familiarity with wind triangle math.
- Battery-free operation works anywhere, including remote exam rooms.
- Lightweight plastic construction is easy to carry in a flight bag.

Not Your Match When
Pilots needing a tougher daily-carry E6B will find the ASA E6B Metal Flight Computer a more durable long-term companion.
Many student pilots find traditional monochrome E6Bs visually flat, which is exactly the problem the ASA Color E6B was designed to fix. The aluminum body carries color accents that highlight each step of a calculation, guiding your eye through wind correction, fuel burn, and airspeed conversions. Solid aluminum construction means this is a tool built for years of cockpit use.
The color-coding approach helps visual learners track which value lands on which ring, reducing the misreads that plague first-time E6B users. For pilots upgrading from a basic plastic model like the SimCoach above, this feels like a meaningful step up in both feel and clarity. Most owners find the visual system cuts their learning curve noticeably.
Points In Its Favor
- Color-coded layout simplifies tracking complex multi-step calculations.
- Solid aluminum body delivers premium durability for daily cockpit use.
- Approved for FAA written exams alongside standard monochrome E6Bs.
- Visual system lowers the learning curve for new student pilots.
A Few Limitations
- Premium aluminum adds noticeable weight to your flight bag.

What To Weigh Before Choosing Flight Computers
Manual E6Bs versus digital calculators is the first fork in the road. Manual slide rules build real understanding of wind correction and fuel math, which pays off during oral exams, but they ask for your attention. Digital units like the ASA CX-3 Flight Computer deliver faster answers and shave time off complex planning, though you trade tactile learning for battery dependency.
Chart scale coverage matters more than most new pilots expect. Sectional charts at 1:500,000, WAC charts at 1:1,000,000, and terminal area charts at 1:250,000 are the three references you’ll encounter across training, so a plotter handling all three saves tool-swapping mid-flight. Magnetic variation conversion is another quiet but essential function when working true versus magnetic courses.
Build material affects both longevity and feel. Aluminum E6Bs survive decades of kneeboard abuse, while plastic or resin models cost less but show wear faster. Cockpit environment matters here too: hot unpressurized cabins can warp lower-grade plastics, so a heat-rated body becomes valuable in summer flying. Consider how often you’ll actually use the tool, and what conditions it will live in, before settling on a material.
Factors To Consider When Choosing Flight Computers
Pick your tool based on the training stage you’re entering. Ground school beginners benefit most from manual E6Bs that teach the math, while students preparing for checkrides appreciate digital speed. Match the plotter scales to the charts you actually fly with, since extra unused scales add bulk without value. If you fly in warm climates, prioritize heat-resistant plastics or aluminum over budget materials that may warp under cockpit sun.
Smart Considerations Across These Picks
Wrong Turns To Avoid
A common slip is buying a fancy digital calculator before you’ve learned the underlying math, which leaves you stranded when batteries die mid-exam. Another trap is grabbing a plotter with scales you’ll never use, like WAC references when you fly only sectional routes. Skip the temptation to match your instructor’s exact tool and focus instead on whether the scale coverage and build match your actual flying.
Where The Extra Money Goes
Premium aluminum E6Bs cost more because the body survives decades of daily kneeboard use, while budget plastic models often need replacing after a few hard training seasons. Color-coded markings add a real learning benefit for visual learners, justifying the upgrade over monochrome versions. Bundled kits like the SimCoach plotter set trade a little component refinement for a coordinated, ready-to-use package that suits early training programs.
Frequently Asked Questions
What is a flight computer used for?
A flight computer handles the math pilots can’t easily do in their heads, from wind correction angles and true airspeed to fuel burn and time en route. Manual versions use a slide rule, while digital models compute the same values electronically.
Do I need an E6B if I have a digital calculator app?
Apps offer convenience but batteries die, and exams often restrict electronic devices. A standalone E6B remains the reliable backup and accepted exam tool, plus the manual practice reinforces the underlying math.
Can one plotter handle every chart type I fly?
Most student pilots work with sectional and terminal area charts, and a dual-scale plotter covers both. If you also reference WAC charts for longer cross-countries, a triple-scale model avoids tool swaps.
Is aluminum really better than plastic for an E6B?
Aluminum E6Bs survive years of kneeboard abuse and rough handling, while plastic models cost less but show wear faster. For pilots keeping the tool across multiple certificates, aluminum typically outlasts plastic.
How long does it take to learn an E6B?
Most students get comfortable with basic time, speed, and distance calculations within a few weeks of regular practice. Wind triangle work takes longer, often a couple of months of consistent kneeboard drills before the steps feel automatic.
Closing Remarks
Eight flight computers, eight different ways to approach the same cockpit math. Manual E6Bs build real understanding, digital calculators save time, and the right plotter keeps your chart work accurate. Match the tool to your training stage, your cockpit environment, and the charts you actually fly, and the rest takes care of itself.
